By rights, the Alien franchise should be dead by now, all curled up on its back like a big dead spider, flambéed by the flamethrower of critical ire. How many other movie series would be allowed so many misses and still get invited back to the plate for another swing? Throughout its various iterations since the 90s - sequels, prequels, versus match-ups - the Alien franchise has succeeded only in corroding its own legacy. Even 2012's promising Prometheus, directed by franchise progenitor Ridley Scott, fell short of expectations thanks to its entire cast suffering total frontal lobotomies in the third act. Well, the rot stops here. In Alien: Covenant, Ridley Scott has directed the best Alien movie of the past 30 years, and although that isn't exactly a glowing compliment, know this: not only does Covenant deliver a payload of short, sharp scares and atmosphere in spades, it course-corrects the franchise as a whole, retroactively making Prometheus feel like a better movie too.
